          Abstract

          Neste estudo observou-se que os tegumentos seminais de Caesalpinia ferrea, C. pyramidalis, Senna martiana e S. spectabilis var. excelsa estão compostos de um estrato de macrosclereídes, revestido por cutícula e subcutícula, seguido por uma camada de osteosclereídes, parênquima esclerificado e camada interna também de osteosclereídes. A impermeabilidade dos tegumentos seminais, possivelmente, se restringe à região das macroesclereídes.

          Translated abstract

          According to this paper, the seminal coats of Caesalpinia ferrea, C. pyramidalis, Senna martiana and S. spectabilis var. excelsa were composed of one layer of macrosclereids, coated by a cuticle and a subcuticle layer, followed by a layer of osteosclereids, sclerified parenchyma and another inner layer of osteosclereids. The impermeability of these seed seminal coats is probably restricted to the macrosclereids region.
